Agilent 7820 GC Service
Remove the top EPC module cover and the left side panel on the
GC.
Remove the inlet cover.
Disconnect the split vent line from the inlet and from the trap
canister. At the trap end, use two wrenches against each other
to prevent the trap body from rotating.
When removing/attaching the split vent line at its
trap canister, always use one wrench to support the
canister fitting and one to tighten the nut.
Failure to do this could break the seal within the
canister.
Remove the split vent line for cleaning or replacement.
Replacement is the reverse of these steps.
